The "Strap Keeper" provides the solid connection between your guitar and strap that you have been longing for. "Strap Keepers" are easily installed and readily removed. They fit all standard endpin type strap jacks and guitar straps. The "Strap Keeper" will not interfere with the use of standard cables or endpin type preamps. The Strap Keeper 2 is for use with Taylor and Takamine-style endpin jacks.
